Description

Technical Field

[0001] The utility model relates to the technical field of PCB production and processing related equipment, in particular to a PCB clamp capable of detecting pressure in real time. Background Art

[0002] In the process of producing and processing PCB boards, it is necessary to clamp and position the PCB board by a PCB clamp, so as to facilitate the transportation of the PCB board to various different workstations for corresponding processing. In the prior art, PCB clamps generally use multiple spring clamps to clamp the PCB board, so there are certain requirements for the clamping force of the spring clamps. Since long-term use will cause fatigue of the spring clamps and reduce the clamping force, if the clamping pressure of the spring clamps is too small, it is easy to cause the clamping looseness, and even there is a risk of causing the PCB board to fall. For the pressure detection of the spring clamps, it is generally necessary to remove the spring clamps and detect them in the detection equipment, which is complicated to operate, and it is impossible to timely detect the changes in the clamping pressure of the spring clamps in normal work, and it is difficult to avoid abnormal situations in time, which has certain safety hazards. In addition, if the clamping pressure of the spring clamps is too large, it is easy to cause indentations, scratches and other damages on the surface of the PCB board, causing the surface of the PCB board to be damaged.

[0003] Therefore, the prior art has defects and needs to be improved. Utility Model Content

[0004] The utility model aims to overcome the deficiencies of the prior art and provide a PCB clamp capable of detecting pressure in real time.

[0005] The technical solution of the utility model is as follows: a PCB clamp for real-time pressure detection is provided, comprising: a clamp frame, spring clips evenly distributed around the clamp frame, and a pressure sensor arranged on the clamping surface of the spring clip.

[0006] Furthermore, the pressure sensor is connected to a control system.

[0007] Furthermore, a plurality of traceability identification modules are arranged on the fixture frame.

[0008] Furthermore, the traceability identification module adopts a QR code label.

[0009] Furthermore, the traceability identification module adopts an RFID tag.

[0010] Furthermore, a clamping surface of the spring clamp is provided with a soft rubber clamping block, and the soft rubber clamping block is in contact with the pressure sensor.

[0011] By adopting the above scheme, the utility model clamps and fixes the PCB board by spring clamps arranged around the clamp frame, and when the PCB board is clamped, the clamping pressure applied by the spring clamp on the PCB board is detected by the pressure sensor in the clamping state, and the pressure output size of the spring clamp is measured, which is convenient for the operator to adjust the clamping pressure size of the spring clamp or replace the spring clamp, thereby meeting the detection of the clamping pressure while clamping, avoiding the PCB board from falling off or the surface of the PCB board being damaged due to excessive pressure during the process of clamping and transporting the PCB board, and improving the overall safety. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1 It is a structural schematic diagram of the utility model. DETAILED DESCRIPTION

[0013] The present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0014] See also Figure 1 The utility model provides a PCB clamp for real-time pressure detection, comprising: a clamp frame 1, spring clips 2 evenly distributed around the clamp frame 1, and a pressure sensor arranged on a clamping surface of the spring clips 2.

[0015] The PCB board is clamped and fixed by the spring clamps 2 arranged around the clamp frame 1, and when the PCB board 4 is clamped, the clamping pressure applied by the spring clamps 2 to the PCB board 4 is detected by the pressure sensor in the clamping state, and the pressure output size of the spring clamp 2 is measured, which is convenient for the operator to adjust the clamping pressure size of the spring clamp 2 or replace the spring clamp 2, so as to meet the clamping pressure detection while clamping, avoid the PCB board 4 from falling off or the surface of the PCB board 4 being damaged due to excessive pressure during the process of clamping and transporting the PCB board 4, and improve the overall safety.

[0016] The pressure sensor is connected to a control system. By feeding back the pressure information detected by the pressure sensor to the control system, it is convenient to query the clamping pressure of the corresponding clamp or spring clamp 2 on the PCB board in real time in the control system, thereby avoiding failures and facilitating the prediction and location of potential faulty clamps. At the same time, according to the clamping pressure data information of the clamp, it can be integrated with the PCB information to establish a product information database, provide the best arrangement for the production plan, and improve the production efficiency and quality of the product.

[0017] The fixture frame 1 is provided with a plurality of traceability identification modules 3. The traceability identification modules 3 bind the fixture pressure detection information with the information in the database, so as to facilitate the detection and fault avoidance of the pressure data of each spring clamp 2 of the current fixture, and also facilitate the matching with the production information of the PCB board 4 clamped by the fixture, so as to perform traceability management on the production process of the PCB board 4.

[0018] In some embodiments, the traceability identification module 3 uses a QR code label. The QR code information in the QR code label on the fixture frame 1 is bound to the information entered into the database of the fixture in the control system. When the QR code on the fixture frame 1 is scanned by the code scanning module, the fixture data information page can be directly jumped to the real-time clamping pressure and historical clamping pressure of each spring clamp 2 on the fixture frame 1.

[0019] In some embodiments, the traceability identification module 3 uses an RFID tag. The RFID tag on the fixture frame 1 is bound to the information of the fixture entered into the database in the control system. When the radio frequency transmission module establishes a connection with the RFID tag, the fixture data information page can be directly jumped to the real-time clamping pressure and historical clamping pressure of each spring clamp 2 on the fixture frame 1.

[0020] In some embodiments, the clamping surface of the spring clamp 2 is provided with a soft-glue clamping block, and the soft-glue clamping block is in contact with the pressure sensor. The soft-glue clamping block contacts the PCB board 4 during the clamping process, thereby avoiding damage to the surface of the PCB board 4 and ensuring the surface yield of the PCB board 4. At the same time, the pressure is transmitted to the pressure sensor through the soft-glue clamping block, thereby meeting the need to detect the pressure value applied to the PCB board 4. In addition, since the friction force generated on the surface of the soft-glue clamping block is relatively large, the stability of the clamping of the PCB board 4 can be effectively guaranteed, and the PCB board 4 can be prevented from falling off from the clamping position of the spring clamp 2.

[0021] In summary, the utility model clamps and fixes the PCB board by means of spring clips arranged around the clamp frame, and when the PCB board is clamped, the clamping pressure applied by the spring clips to the PCB board is detected by means of a pressure sensor in the clamping state, and the pressure output of the spring clip is measured, so that the operator can adjust the clamping pressure of the spring clip or replace the spring clip, thereby satisfying the detection of the clamping pressure while clamping, avoiding the PCB board from falling off or the surface of the PCB board from being damaged due to excessive pressure during the process of clamping and transporting the PCB board, and improving the overall safety.

[0022] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
